QRS Voltage Criteria for Posterior Unipolar Chest Leads in a Normal Population

QRS Voltage Criteria for Posterior Unipolar Chest Leads in a Normal Population

1)The range and upper limit of normal QRS voltage criteria for posterior chest leads (V7, V8 and V9) were derived from 50 normal subjects.2)One third of the study group had a significant Q wave in Ve.3)The mean height of the R wave in V7, V8 and V9 was 7.2 mm, 5.7 mm and 4.1 mm, respectively.
